export default createAppContainer(TabNavigator);

Answer 1

you can use MaterialCommunityIcons like this:

import { MaterialCommunityIcons } from 'react-native-vector-icons';

<Tab.Screen
    name="Feed"
    component={Feed}
    options={{
      tabBarLabel: 'Home',
      tabBarIcon: ({ color, size }) => (
        <MaterialCommunityIcons name="home" color={color} size={size} />
      ),
    }}
  />

You can find more info here: https://reactnavigation.org/docs/bottom-tab-navigator/

Answer 2

you can try define the icon in navigationOptions this is docs example

export default createBottomTabNavigator(
  {
    Home: HomeScreen,
    Settings: SettingsScreen,
  },
  {
    navigationOptions: ({ navigation }) => ({
      tabBarIcon: ({ focused, horizontal, tintColor }) => {
        const { routeName } = navigation.state;
        let iconName;
        if (routeName === 'Home') {
          iconName = `ios-information-circle${focused ? '' : '-outline'}`;
        } else if (routeName === 'Settings') {
          iconName = `ios-options${focused ? '' : '-outline'}`;
        }

        // You can return any component that you like here! We usually use an
        // icon component from react-native-vector-icons
        return <Ionicons name={iconName} size={horizontal ? 20 : 25} color={tintColor} />;
      },
    }),
    tabBarOptions: {
      activeTintColor: 'tomato',
      inactiveTintColor: 'gray',
    },
  }
);

with routeName you can put the icon

   if (routeName === 'Home') {
     return <Ionicons name={iconName} size={horizontal ? 20 : 25} color={tintColor} />;
   }
